The Influence Of Pre-Pregnancy Weight And Weight Gain On Obstetric Complications And Pregnancy Outcome

Objective: To investigate the influence of pre-pregnancy weight and weight gain on obstetric complication and delivery outcome,that the result will be used clinical。Methods:564 cases of primipara were divided into four groups according to pre-pregnancy Body mass index: thin group(BMI<18.7),normal weight group(18.5≤BMI≤23.9) , over weight group(24≤BMI≤27.9),obese group(BMI≥28),but the simple size of obese group is small, so combined the obese group and over weight group. They were divided into three groups according to BMI increase during pregnancy:A group(△BMI<4),B group(4≤△BMI≤6),C group(△BMI>6).It is to compare the relationship of obstetric complication and delivery outcome between different groups.Results:①Pregnancy-induced hypertension were compared statistically significant difference(P<0.05)between thin group ,normal group, overweight group, but GDM between normal group and overweight group has no significant difference. Maybe because many people have be awared that pregnancy obesity is a problem.②Pre-pregnancy weight premature neonatal in each group, no significant differences in occurrence of fetal macrosomia, mainly with weight gain during pregnancy, pre-pregnancy weight in each group with a significant difference between the incidence of neonatal asphyxia, pre-pregnancy obesity is a risk factor for neonatal asphyxia.③Cesarean section rate, vaginal delivery and wound liquefaction rate among all pre-pregnancy body mass groups compared with statistical difference (P <0.05). Obesity is risk factors of wound fat liquefaction after cesarean section④Pregnancy induced hypertension and neonatal macrosomia between the groups, compared with statistical difference (P <0.05) , increased incidence. Weight gain during pregnancy gestational diabetes between the groups and impaired glucose tolerance, the difference was not significant, may be the cause of gestational diabetes with insulin resistance and glucose abnormalities during pregnancy has been found that focus on dietary adjustments.⑤Weight gain during pregnancy cesarean section rate among all groups, postoperative wound fat liquefaction compared with statistical difference (P <0.05). with weight gaining, increased incidence of caesarean section. The vaginal delivery decreased with increasing body weight.Conclution: The pre-pregnancy obesity and weight gain during pregnancy can increase risks of adverse outcomes of pregnancy such as the pregnancy induced hypertension rate, postoperative wound fat liquefaction, large child, neonatal asphyxia, pregnancy weight should be controlled and do early prevention.
